If you could give me an explanation, that would be great. Perhaps some laws or principles that I could follow for an upcoming exam? I don't quite understand the relationship between Watts and Calories in the mathematical/theoretical sense.

1 calorie = 4.184 Joules
1 Joule = 1 watt-second, so
1calorie (C) = 4.184 w-s
(100 C/hr)(1 hr/3600 s)(4.184 w-s/C) =
0.11622... watts

1 calorie = 4.184 Joules
1 Joule = 1 watt-second
1calorie = 4.184 w-s
(100 C/hr)(1 hr/3600 s)(4.184 w-s/C) =
0.11622watt
1 calorie is the amt of heat req to raise the temp of 1g of water through 1 deg C.

the flexibility plant produces one hundred MWatts. you activate (a million) one hundred Watt easy bulb, and you're utilising one hundred of the great one hundred MWatts (ignore on the subject of the time for now) you activate (2) one hundred Watt easy bulbs, and you're utilising two hundred of the great one hundred MWatts. Now the flexibility employer desires to value you something for utilising the two hundred Watts of ability, so as that they settle directly to value you with the help of the hour, so now they might desire to maintain tract of what proportion hours you circulate away those lights on, through fact jointly as you're utilising those two hundred Watts of their ability no person else can use them. so as that they put in a meter that tracks your use of their Watts, and multiplies it circumstances the form of hours which you used those Watts. Then they deliver you an remarkable vast bill for all the killowats which you used. So while they say they're putting in a one hundred MWatt ability plant, that is a diploma of the non-provide up ability output. in case you will possibly activate a one hundred MWatt easy bulb, you will possibly could pay for all the flexibility they produced, until you grew to become the easy off.

100 calories* 4.1868Joules/calorie*Nm/Joules = 418.68Nm
basically, for every calorie, there is 4.17 Joules of energy. One joule is the same as a Nm
Power is the energy used in a unit of time; in watts, that would be Nm/s
1hr*60min/hr*60sec/min = 3600s
418.68Nm/3600s = .1163 Nm/s or .1163 watts

Don't forget that 1 Calorie = 1,000 calories. Its an odd convention, and easy to miss. If he produced only 100 calories per hour he would be dead.
